Problem with Gnome Extensions

Hi all,

The only Gnome extension I use on other OS'es (Arch, OpenBSD) is a builtin one called "Applications Menu" that (surprise!) gives you a menu labeled "Applications" in the upper left-hand corner.

Anyhow, as I'm new to FreeBSD, I tried setting this up on my Thinkpad x230 and get a weird behavior. There is a triangle with an exclamation point in it to the right of the line in Tweak Tool and when I hover over it, the tooltip says "Error Loading Extension".

Any ideas what I can do to fix this or at least troubleshoot it further?

This is why I love open source software so much! The community!!!

Thank you rufwoof. I really appreciate the help!!!
